To all whom it may concern."

Be it known that l[, Cnrrronn A. llv, a

citizen of the United States, residing at San enable others skilled in the artto which it 'appertains to make and use the same.

This invention has for its object to provide 'an improved pedal propelled vehicle, which may be easily 1 steered and rapidly operated by the occupant who assumes a standing position. v Another object is the provision of means for transmitting the power from the pedals to the rear axle of the vehicle, and including means adapted for adjustment to permit the operator to easily ascend steep grades.

ith these and other objects in view, the invention consists in the novel construction, combination and arrangement of parts as willbe hereinar s ecitlcally described, claimed and illustrate in the accompanyin drawings, in which: i i re 1 represents a top plan view of the peda operated vehicle,

Fig. 2 represents a side elevation thereof, partly in section,

Fig. 3 represents a detail sectional view on the e 3-3 of Fig. l,

Fig. 4t represents a plan view or a modified type c the pedal propelled vehicle,

Fig. 5 represents a side elevation thereof, partly in section, and I o Fig. 6 represents a transverse sectional view on the line 6- -6 of Fig. l.

Referring wherein similar reference numerals desi nate corresponding parts throughout -t e several views, the numeral 5 indicates a platform, which is mcured at its rear end to the a axle housin t, in which is rotatahly supported the rear'axle 7, carrying the rear wheels 8, which are arran ed upon opposite sides of the platform 5. l front end of the platform. 5 is supported upon a a wheel 9, which is rotatably met- .to the drawings in detail,

ed upon a shaft 10 secured in the; lower blfurcated terminal '11 of the steering post 12, which extends upwardly through the platform 5 and through the steering post housing 13 secured to the platform. A

steering wheel It is secured in the upper terminal of the steering post 12 and is designed to be .operated to steer the vehicle.

A cross bar 15 is secured adjacent the forward extremity of the platform 5 and is pivotally connected by hinges 16 wit a pair of pedals 17, which extend rearwa-rdly and terminate in spaced relation to the rear axle housing. 6. The edals 17 are normally retained in elevate position'by the tension of springs 18.

Gear housings 19 are connected with the axle housing 16 on opposite sides of the rear terminal of the platfo 5 and house the pinions 20, which are rotatablymoun upon the axle 7 and are locked for rotation in one direction therewith by the pawls 21,

pivotally secured to the inlons 20 and the ratchet wheels 22 rigid y secured to the axle 7.

A lever 23 is pivotally secured at 2d to each longitudinal edge of the latform 5,

and extends rearwardly into t e adjacent gear housing 19. 'lhe'rear terminal of the lever is connected with a gear scent 25, which meshes with the pinion 20-and projects forwardly from its 'votal axis be tween the platform 5 and the pedal l7, being received within a recess 2t formed in the inner edge of the latter.

Sleeves 27 are slidably mounted upon the reduced forward terminals of the levers 23 and are rigidly fastened "in adjusted'position thereon by set screws 28. laterally projecting pins 29 are fcrmedinte with the sleeves 27 and are slidably in elongated slots 30 formed adjacent the rear terminals of the pedals 17.

In operation, the neon ant alterna treads upon the two peda s 17, which a normally retained in elevated positionhy the. tension of springs 18, the doward mo ement of each pedal bein tnsmitted to the co-acting pinion 21) carried by the rear le 7 throh the pin 22, lever, andltd . indicated at 48,-

gear segment 25. The pawls 21 co-act with the ratchet wheels 22, during rotary movement of the, pinions 20., to drive the axle 7 in a direction to propel the vehicle forwardly, and during the return or u ward movement of the pedals, underthe in uence of the springs 18, the pawls 21'ride idly over the teeth of the ratchet wheels 22. By adjusting the sleeves 27 longitudinally of the levers 23, the leverage exerted bythe pedals 17 may be varied, as desired, in order to permit the occupant of the vehicle to' ascend comparatively steep grades with a minimum exertion of power.

Referring to the modification of the invention illustrated in Figs. 4 and 6, the numeral 31 indicates a platform which is secured adjacent its rear end to an axle housing 32, in which is rotatably supported an axle 33 carrying the rear or drive wheels 34.

The front end of the platform is supported .upon a steering wheel 35, which is journaled 1n the bifurcated lower terminal of the steering post carrying the steering wheel 37.

single sprocket wheel 38 is non-rotatably secured upon the rear axle 33 and supports a sprocket chain 39, which extends forwardly under the platform 31 and is trained over a sprocket wheel 40 non-rotatably secured upon a shaft 41.

The shaft 41 is supported in a housing 42, which is secured under the platform 31 and constitutes a housing for the sprocket wheel 38,.chain 39, shaft 41 and parts associated therewith. 1

A pair of pedals 43 are pivotally secured at 44 to the ongitudinal edges of the platform 31 and are provided with reduced forward ends 45 formed with longitudinally elongated slots 46, receiving the pins 47. The medial portion of each pin 47, which is disposed within the slot 46, is squared, as so as to secure the pin against rotary movement in the slot and the outer terminal of the pin is formed with external screw threads 49 upon which is fitted a nut 50, adapted to draw the integral flange 51, carried by the pin, into frictional en agement with the iuner surface of the reduced terminal 45 of the pedal and thus rigidly secure the pin in adjusted position longitudinally of the pedal extension.

he inner terminals of the pins are slidably mounted in slots 52 formed in a pair of levers 53, which are pivotally secured at 54 to the housing 42, and are adapted to be oscillated by the pedals 43, during operation of the latter. By adjusting the pins 47 longitudinally of the pedals, the leverage exerted by the pedals upon the levers may be varied, as desired, in order to permit the operator of the vehicle to more easily propel the vehicle upon hills.

e forward terminals of the levers 53 are connected with mesh with pinions 56 rotatably mounted upon the shaft 41 on opposite sides of the sprocket wheel 40. The pinions 56 are locked for rotation with the shaft 41 to drive the gear wheels 34 forwardlyby pawls 57, pivotally secured to the pinions 56 and ratchet wheels 58, rigidly secured 'to the shaft 41.
